I have seperate my website to 4 VPS's to be working in each process like
vps_1 ( Master Database ).
vps_2 ( Website Files ).
vps_3 ( Images files).
vps_$ ( Nginx www.website).
All nodes don't have any kind of control panel. ex: cPanel, DirectAdmin.. etc
Only you will work through SSH.
Now all are connected and everything looks to be okay, but what i have today is that the website admin panel cannot display any page there! cannot click/open PHP & MySQL data in admin panel.
The website are loading the news fine with no issue, but the only issue is with the admin panel, i believe it's from the same Website files ( where the admin files hosted ), we may need to reinstall a new VPS and build a new custom PHP with MySQL and connect it to the master database VPS.
Hence i need someone to try to fix it without reinstalling the VPS again.
After we fix that, i need him to Firewalled my VPS's in 2 nodes, ( there will be for each website 4 VPS's. so the work will be on 2 websites, with 8 VPS's should be Firewalled and i prefer who have his own custom private Firewall against SYN FLOOD attack because sometime we recieved this kind of attack, hence after all we need to install mod_security on 2 VPS ( for 2 different websites ).
Please make sure to start from today in this project and must be finished with in 1/2 business days, not more or the project will be canceled from you!
Thank you for your time!
